1. ROAD CONSTRUCTION
1.1 Read and translate the text
A road is a thoroughfare, route, or way on land between two places, which has been paved or otherwise improved to allow travel by some conveyance, including a horse, cart, or motor vehicle. Roads consist of one, or sometimes two, roadways (British English: carriageways) each with one or more lanes and also any associated sidewalks(British English: pavement) and road verges, Roads that are available for use by the public may be referred to as public roads or highways.
For purposes of international statistical comparison, the Organisation for Economic Co-operation and Development(OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels," which includes "bridges, tunnels, supporting structures, junctions, crossings, interchanges, and toll roads, but not cycle paths. In urban areas roads may diverge through a city or village and be named as streets, serving a dual function as urban space easement and route.
Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel. Historically many roads were simply recognizable routes without any formal construction or maintenance.

In the United Kingdom there is some ambiguity between the terms highway and road.
The Highway code details rules for "road users". For the purposes of the English law, Highways Act 1980, which covers England and Wales but not Scotland or Northern Ireland, the term road is defined to be "any length of highway or of any other road to which the public has access, and includes bridges over which a road passes.
This includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks.
Vehicle Excise Duty, a road use tax, is payable on some vehicles used on the public road.

2. Road Construction 2
2.1 Read and translate the text
The definition of a road depends on the definition of a highway, however there is no formal definition for a highway in the relevant Act. A 1984 ruling said "the land over which a public right of way exists is known as a highway; and although most highways have been made up into roads, and most easements of way exist over footpaths, the presence or absence of a made road has nothing to do with the distinction. Another legal view is that while a highway historically included footpaths, bridleways, driftways, etc., it can now be used to mean those ways that allow the movement of motor-vehicles, and the term rights of way can be used to cover the wider usage.
Road construction requires the creation of a continuous right-of-way, overcoming geographic obstacles and having grades low enough to permit vehicle or foot travel. and may be required to meet standards set by law or official guidelines. The process is often begun with the removal of earth and rock by digging or blasting, construction of embankments, bridges and tunnels, and removal of vegetation (this may involve deforestation) and followed by the laying of pavement material. A variety of road building equipment is employed in road building.
Old road surfaces, fences, and buildings may need to be removed before construction can begin. Trees in the road construction area may be marked for retention. These protected trees should not have the topsoil within the area of the tree's drip line removed and the area should be kept clear of construction material and equipment. Compensation or replacement may be required if a protected tree is damaged. Much of the vegetation may be mulched and put aside for use during reinstatement. The topsoil is usually stripped and stockpiled nearby for rehabilitation of newly constructed embankments along the road. Stumps and roots are removed and holes filled as required before the earthwork begins. Final rehabilitation after road construction is completed will include seeding, planting, watering and other activities to reinstate the area to be consistent with the untouched surrounding areas.

3. Road Construction 3
3.1 Read and translate the text
Processes during earthwork include excavation, removal of material to spoil, filling, compacting, construction and trimming. If rock or other unsuitable material is discovered it is removed, moisture content is managed and replaced with standard fill compacted to meet the design requirements (generally 90-95% relative compaction). blasting is not frequently used to excavate the road bed as the intact rock structure forms an ideal road base. When a depression must be filled to come up to the road grade the native bed is compacted after the topsoil has been removed. The fill is made by the "compacted layer method" where a layer of fill is spread then compacted to specifications, the process is repeated until the desired grade is reached.
Like all structures, roads deteriorate over time. Deterioration is primarily due to accumulated damage from vehicles, however environmental effects such as frost heaves, thermal cracking and oxidation often contribute. According to a series of experiments carried out in the late 1950s, called the AASHO Road Test, it was empirically determined that the effective damage done to the road is roughly proportional to the Fourth power of axle weight. A typical tractor-trailer weighing 80,000 pounds (36.287 t) with 8,000 pounds (3.629 t) on the steer axle and 36,000 pounds (16.329 t) on both of the tandem axle groups is expected to do 7,800 times more damage than a passenger vehicle with 2,000 pounds (0.907 t) on each axle. Potholes on roads are caused by rain damage and vehicle braking or related construction works. Failure to maintain roads properly can create significant costs to society, in a 2009 report released by the American Association of State Highway and Transportation Officials (USA) about 50% of the roads in the USA are in bad condition with urban areas worse. The report estimates that urban drivers pay an average of $746/year on vehicle repairs while the average US motorist pays about $335/year. In contrast, the average motorist pays about $171/year in road maintenance taxes (based on 600 gallons/ye

4.1 Read and translate the text
With unsealed roads, naturally well bonded fine materials such as sand-clays and granite-sands can be used. These aggregate mixtures should contain both wear resistant stone and natural binder, such as clay. For the surface course the maximum stone size should be less than 40 mm. Larger stones interfere with maintenance of the surface and give a poorer ride. On the other hand, an excess of fines can produce a surface which is slick when wet and dusty when dry. To control dust such techniques are used: water spraying, application of modified bitumen to the road surface, use of calcium chloride and others. All these techniques are relatively unsatisfactory and so road surfaces are usually sealed with a thin bitumen and stone film. In addition to suppressing dust, the initial sealing of an unbound pavement will reduce the moisture content and protect the pavement materials from damage due to traffic, wind and water and water erosion. From a user's viewpoint, sealing provides a better driving surface.
The process of sealing (or seal coating, or surface dressing) is the application to the surface of a thin layer of bitumen into which aggregate is then incorporated. In most cases the bitumen is applied by spraying and the one-sized aggregate is then rolled in.
The aggregate pieces protrude both above the bitumen film, providing surface texture and protection the bitumen film from traffic damage; and below the film into the base course, to provide bearing independent of the bitumen. The aggregate placement is subsequently rearranged by traffic action.
The three types of spray seals are:
1. One application of binder and one layer of aggregate;
2. One application of binder and two layers of aggregate;
3. Two applications of binder and two layers of aggregate.
Spray seal construction is best undertaken in warm, dry weather. The spraying equipment must be capable of providing uniform spray.

5. Flexible (asphaltic concrete) pavements
5.1 Read and translate the text
Asphaltic concrete surface layers can have thickness down to 25 mm. Full depth asphalt is a term used to describe a pavement in which all the courses are comprised of asphaltic concrete.
Asphalt concrete is a bitumen-aggregate mix produced at a plant or on site. A plant mix is a mixture of bitumen, as a binder, and mineral aggregates, prepared hot at a mixing plant and maintained at about 150°. Fly ash, Portland cement and ground limestone are used as fine fillers.
The objective of asphalt mix design is to determine the proportion of bitumen, filler and aggregate which will produce a mix which can be spread and compacted, will have a suitable surface with respect to skid resistance and which will be stiff (particularly in hot weather), durable and waterproof. It is common to base the structural design of the pavement on properties obtained from tests on the proposed mix.
Bituminous mixtures require compacting during placement. The main purposes of compaction are (1) to increase stiffness and strength, and (2) to protect mixes from rapid bitumen hardening.
The basic equipment consists of an asphalt mixing plant, an asphalt paver, a roller and a finisher.
If strength or stiffness of pavement must be corrected, a new layer of material is required. This process is called resheeting and the added layers are called overlays. A thin overlay of asphaltic concrete can be used for the correction of surface deteriorations - roughness, excessive permeability, low skid resistance, etc. These overlays are generally either 25 or 40 mm thick. The overlays are produced by applying a layer of plant mix to the road surface.

6. Maintenance of roads
6.1 Read and translate the text
The behavoiur of a road passes through a number of stages. After construction has been completed and the road is in operation, it enters a setting down stage which may last for one or two years. During this time construction imperfections become evident, particularly after a wet season. Such faults can usually be corrected by routine maintenance means such as minor patching and pot-hole repair.
As a road is subjected to traffic it is progressively damaged. The road enters its next life cycle stage when the surface deficiencies have worsened to the extend that they require some major repair effort, usually in the form of resealing or overlaying.
The final stage in the life of the road occurs when deformation-related deficiencies, indicating structural failure, begin to occur. These can only be rectified by major rehabilitation of the road structure such as ripping up the existing base course and either replacing it or adding additional material.
The role of experience and judgement in pavement design, construction and maintenance is so great that good engineering practice demands that the performance of all roads be consistently evaluated. The basic aims of this evaluation are:
1. To check the pavement function and performance;
2. To provide guidance for planning maintenance;
3. To detect condition changes from one year to the next.

§ must be trained in traffic control techniques
§ must have a valid Washington Traffic Control Flagger card (or card from a state with reciprocal flagger training)
Safety within the Work Zone:
Temporary Traffic Control Plan
In the Temporary Traffic Control zone, construction vehicles and equipment moving inside create a risk to workers on foot requiring additional protection planning and policies to minimize backing-up maneuvers in the “activity area”
The Temporary Traffic Control “Activity Area” is the section of the highway where the work activity takes place. It is comprised of the work space, the traffic space, and the buffer space.
The “work space” is that portion of the road closed and set aside for equipment, workers, and material. Work spaces are usually delineated apart from the traffic space, to exclude vehicles and pedestrians, by channelizing devices or temporary barriers and signs.

13. The history of bridge and tunnel building. Bridges I
13.1 Read and translate the text
One of the outstanding statesmen once said in his speech, "There can be little doubt that in many ways the story of bridge-building is the story of civilization. By it we can readily measure an important part of a people's progress." Great rivers are important rneans of communication for in many parts of the world they have been, and still are, the chief roads. But they are also barriers to communication and people have always been concerned with finding ways to cross them.
For hundreds of years men have built bridges over fast-following rivers or deep and rocky canyons. Early mаn probably got the idea of a bridge from a tree fallen across a stream. From this, at a later stage, a bridge on a very simple bracket or cantilever principle1 was evolved. Timber beams were embedded into the banks on each side of the river with their ends extending over the water. These made simple supports for a central beam reaching across from one bracket to the other. Bridges of this type are still used in Japan, and in India. A simple bridge on the suspension principle2 was made by early man by means of ropes, and is still used in countries such as Tibet. Two parallel ropes suspended from rocks or trees on each bank of the river, with a platform of woven mats laid across them, made a secure crossing. Further ropes as handrails3 were added. When the Spaniards reached South America, they fund that the lncas of Peru used suspension bridges made of six strong cables, four of which supported a platform and two served as rails. All these bridges made possible crossings only over narrow rivers. The type of temporary floating bridge4, the pontoon bridge, has been used for military purposes; military engineers can construct a temporary bridge on this principle, able to carry all the heavy equipment of a modern army, in an extremely short time.
